Background: In addition to manual compression, various vascular closure devices (VCD) are available to seal the puncture site following arterial vascular procedures. Purpose: To evaluate the efficacy and safety of the extravascular MYNX CONTROL closure system for achieving primary hemostasis after femoral arterial access following peripheral arterial procedures, compared to the intravascular FemoSeal Aclosure system. Patients and Methods: A retrospective analysis of consecutive patients who underwent endovascular intervention between April and November 2022 was performed...

This study evaluated the feasibility and safety of imaging-guided deployment of a Mynx Control device (Cordis, Miami Lakes, Florida) at the femoral access. A total of 201 Mynx devices were used under imaging guidance in 137 patients (mean age, 64.18 years ± 13.8; male, 68.6%) between June 2020 and February 2022. A 5-F sheath was used in 176 (87.6%) procedures, a 6-F sheath was used in 17 (8.5%) procedures, and a 7-F sheath was used in 8 (4%) procedures. Indicator errors occurred in 9 (4.5%) procedures...

OBJECTIVES: This article aims to present a prospective study investigating the safety and efficacy of the Mynx Control extravascular closure device (Cordis Corporation, FL, USA), for femoral arterial closure in patients undergoing peripheral arterial procedures. METHODS: Between January 2020 and February 2021, 100 Mynx Control devices were deployed in 91 consecutive patients (mean age: 67.5 ± 16.9 years) who underwent peripheral arterial procedures. We used ultrasound and/or fluoroscopy during Mynx Control deployment and ultrasound post-procedure to detect complications...

The Mynx Control device (Cardinal Healthcare, Dublin, Ohio, USA) was recently licensed and allows for entirely extravascular arteriotomy closure. It uses a polyethylene glycol sealant plug which is absorbed fully within 30 days, alleviating concerns around difficulties with regaining access in future. The Mynx device uses a balloon, inflated within the artery and retracted against the arteriotomy to achieve haemostasis, with the extravascular sealant plug then deployed outside the vessel wall. While the manufacturer's instructions for use do not include utilisation of imaging guidance, we routinely employ fluoroscopic and/or ultrasound to ensure safe use of the device...

We present a case of a common femoral artery repair after losing access to the vessel in a 67-year-old woman using a Mynx-Grip vascular closure device. The hematoma over the right common femoral artery was accessed under fluoroscopic guidance. Then, the balloon of the closure device was inflated inside the artery and pulled back against the origin of the puncture site into the common femoral artery. Finally, the collagen plug was deployed and pressed against the outside of the vessel to occlude the puncture site...

INTRODUCTION: To evaluate the feasibility and safety of the Mynx vascular closure device (VCD) for arteriotomy closure after stent placement near the common femoral artery (CFA) access site. METHODS: A total of 88 patients (73 men; mean age, 72 ± 9.2 years; 136 procedures) who underwent closure of CFA arteriotomy using the Mynx VCD after stent placement in proximal superficial femoral artery (SFA) with antegrade approach, or in common or external iliac artery with retrograde approach were retrospectively studied...

BACKGROUND: Vascular closure devices (VCDs) have become a mainstay in endovascular interventions in recent years. On-label use only allows for retrograde interventions originating at the common femoral artery (CFA). However, off-label use in antegrade and/or superficial femoral artery (SFA) access has become more common in the treatment of peripheral arterial disease. Despite this, there is a paucity of comparative literature assessing individual VCD safety profiles and relative complication risks of CFA vs SFA applications...

Flow diversion technology has revolutionized the treatment of complex anterior circulation cerebral aneurysms. However, vessel tortuosity and atherosclerotic disease may hamper the standard transfemoral access used in these procedures. Percutaneous direct carotid puncture is a viable alternative, but adequate carotid closure must be achieved. Here, we present the first case of a giant partially thrombosed aneurysm of the cavernous internal carotid artery treated with a Pipeline embolization device (PED; ev3 Neurovascular, Irvine, California, USA) via direct carotid puncture...

INTRODUCTION: We aimed to compare the safety and efficacy of 5 arterial closure devices in an outpatient endovascular surgery center. METHODS: We retrospectively reviewed all cases using femoral arterial access performed between January 2012 and December 2013. Five different arterial closure devices (AngioSeal, Perclose, StarClose, ExoSeal, and Mynx) were used by 7 endovascular surgeons. All femoral arteries were accessed with 6F sheaths under ultrasound guidance...

INTRODUCTION: Vascular closure devices (VCDs) are commonly used to achieve hemostasis of arterial access sites, but there is little comparative data on the variety of VCDs currently in clinical use. We reviewed the VCD experience at our institution to determine the safest and most effective VCD. MATERIALS AND METHODS: Retrospective analysis of 907 consecutive arterial procedures in interventional radiology from June 2012 to June 2014 was performed. Five VCDs were used: Angio-Seal (n = 478), FISH (n = 56), Mynx (n = 56), Perclose (n = 61), and Starclose (n = 68)...

The "preclose" technique employing two Perclose (P) devices is well established for large-bore artery (LBA) hemostasis. Occasionally, only one Perclose deploys successfully during the initial preclose because of arterial calcification necessitating the use of the crossover balloon technique to achieve hemostasis at the LBA. We sought to determine if the combined use of one Perclose and either one Angioseal or one Mynx vascular closure device (VCD) is a safe alternative closure technique large-bore arteriotomy closure...

BACKGROUND: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices. METHODS: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n = 894)...

BACKGROUND: The process of assuring the safety of medical devices is constrained by reliance on voluntary reporting of adverse events. We evaluated a strategy of prospective, active surveillance of a national clinical registry to monitor the safety of an implantable vascular-closure device that had a suspected association with increased adverse events after percutaneous coronary intervention (PCI). METHODS: We used an integrated clinical-data surveillance system to conduct a prospective, propensity-matched analysis of the safety of the Mynx vascular-closure device, as compared with alternative approved vascular-closure devices, with data from the CathPCI Registry of the National Cardiovascular Data Registry...

Bailout stenting of the common femoral artery (CFA) may become necessary with failed balloon angioplasty or atherectomy or in case of bleeding requiring a covered stent over the arteriotomy site. Reaccessing the CFA through a previously placed stent may occur during angiography. The safety and effectiveness of applying a closure device, or manual compression to achieve hemostasis through an accessed stented CFA are unknown. All patients in our practice that underwent CFA stenting were identified using billing records for 3 years (January 1, 2010-February 28, 2013)...

BACKGROUND: Femoral artery closure device use following percutaneous cannulation allows earlier mobilization, reduced staff burden, and improved comfort for patients compared with manual compression. The Mynx device (Access Closure, Inc), a novel extravascular closure device, uses a water-soluble non-thrombogenic polyethylene glycol plug. METHODS: We report retrospective analysis of success, complication rates, and associated factors in 432 consecutive patients undergoing elective outpatient coronary angiography in a single United Kingdom center...

OBJECTIVE: We evaluate the prevalence of complications and failure rates between the most commonly used "active" anchoring vascular closure device (VCD), AngioSeal™ and the "passive" anchoring VCD, Mynx™, in all-comers undergoing percutaneous coronary intervention (PCI). METHODS: A total of 4,074 patients between 2008 and 2014, representing an era when both devices were available, were included. Thirty-two percent were acute coronary syndromes (37% STEMI)...

AIMS: Vascular closure device (VCD)-based venous closure has been anecdotally reported, but systematic evaluation of the reparative response of the vessel wall to venous closure is lacking. The need to control groin complications, and minimize risks associated with postponed sheath removal under conditions of persistent anticoagulation, has generated interest in the role of VCDs for venous access closure. We sought to characterize the vessel wall response to venous closure, both acutely and in delayed fashion at 30 days using angiography, ultrasound, and histology...

The Mynx (AccessClosure, Inc) is a vascular closure device that uses extravascular deployment of a self-expanding polyethylene glycol (PEG) sealant delivered during removal of the procedural sheath. An intravascular balloon is inflated at the arteriotomy site to prevent leakage of the sealant into the bloodstream. The complication rate with the Mynx vascular closure device is low, but there have been reports of distal embolization of the sealant. Optimal treatment of this complication is unknown, with limited published data relating only to surgical extraction...

BACKGROUND AND PURPOSE: Percutaneous transfemoral arterial procedures rely on a variety of vascular closure methods. We studied closure success and complications after using the Mynx vascular closure device in cerebral neurovascular procedures. METHODS: We prospectively analyzed patients undergoing diagnostic cerebral angiogram or neurointervention with arteriotomy closure using the Mynx device. Patient demographics and procedural factors were recorded. Statistical analyses compared groups and identified predictors of device failure and complication...
